A security booth at a parking lot shared by Cardinal Spellman High School and Brockton Hospital was spraypainted with racist graffiti sometime Wednesday night or early Thursday morning.

The booth, which is in a satellite parking lot off Quincy Street, was painted with a racial slur, along with the words “go out, we don’t need you,” over and over, said Devis Jean-Jacques, who found the words when he reported to work this morning.

“It was terrible,” he said.

Photos were taken an a police report was filed, Jean-Jacques said, then hospital staff came and painted over the words because they couldn’t be washed off.

Jean-Jacques said he didn’t see who painted the words, but another security guard chased off a group of youths who had smashed a car window in the hospital’s main parking lot Wednesday night.

A hospital spokeswoman said the incident has been reported to Brockton Police, who are investigating. She said to the best of her knowledge nothing like this has happened at the hospital before.
